<div>
    List of credentials to be used by the <code>sshagent</code> step.
    The Pipeline Syntax Snippet Generator will guide the user to select a single credential from the list of available, like this:
<pre>
sshagent(credentials: ['my-credential-id']) {
    // some block
}
</pre>
    The step also accepts a list of credentials, like this:
<pre>
sshagent(credentials: ['my-credential-id', 'my-alternate-credential', 'another-credential']) {
    // some block
}
</pre>
</div>
